Sturgeon: Preference-aware Co-location for Improving Utilization of Power Constrained Computers

2020

Large-scale datacenters often host latency-sensitive services that have stringent Quality-of-Service requirement and experience diurnal load pattern. Co-locating best-effort applications that have no QoS requirement with latency-sensitive services has been widely used to improve the resource …

Accelerating Sparse DNN Models without Hardware-Support via Tile-Wise Sparsity

2020

Network pruning can reduce the high computation cost of deep neural network (DNN) models. However, to maintain their accuracies, sparse models often carry randomly-distributed weights, leading to irregular computations. Consequently, sparse models cannot achieve meaningful …
